BEN Ar.. THOMAS, or PORTLAND, OREGON.

HYDRANT on FAUGET.

Application filed April 24, 1918. Serial No. 230,557.

To all whom t may concern.'

Be it known that I, BEN B. THOMAS, aV

citizen of the United States of America, re-

siding in the city of Portland, in the county of Multnomah, in the State'of Oregon, have invented certain new and useful Improvements in Hydrantsor Faucets, of which the following is a specification, reference being had to the accompanying drawing. n

My invention relates generally to hand controlled devices for checking or regulating the iiow of liquid through a pipe, and specifically to such a device in which the main valve thereof is actuated by the force of the liquid which it controls. By my invention provision is made for carrying the main valve in a barrel that may be inserted into or removed from its outside case at will,

with the object in view' of securing a true fitting valve and seat without the aid of washers or gaskets, and of providing means when necessary for renewal of said valve and'seat without the expense of an entire new fixture.

What constitutes my invention will be hereinafter specified in detail and succinctly set forth in the appended claims.

In the accompanying drawing,

Figure I is a longitudinal central vertical 30 sect-ion of a present preferred form of embodiment of my invention adapted to be used as a washstand fixture, showing the main valve open.

Fig. II is a similar view showing the main valve closed, with relationship of the parts of -the entire mechanism shown to correspond.

Fig. III is an end elevation of the subject matter of Fig. II.

Referring to the numerals on the drawing, 1 indicates the outside case of a fixture of any suitable and preferred design, construction, material, and dimensions. It is shown as attached to a delivery pipe 2, disis designed and adapted to control.

At the end of the case 1 opposite the one which receives the pipe 2 I prefer to provide a screw -plug 4 and to provide within the case adjacent to its union with the pipe 2 a stop-seat 5.

Between the stop-seat 5 and the plug 4 is provided accommodation for a barrel 6 that makes a snug fit within the case in zones 7 and 8, between which the bore of the case is charge from which as through a spout 3 it expanded as indicated by the numeral 9 to admit of'free flow of liquid around it.

The barrel 6 is penetrated by a ring of preferably circular vents 10 which are adapted to be opened, as shown in Fig. I, or to be closed, as shown in Fig. II, by the reciprocation within the barrel of a pistonvalve 12 that is confined within the bore of the barrel with snug slip-lit.

The bore of the barrel 6 is, towards its end opposite the ring of vents 10 as indicated by reference numeral 15, enlarged into a cylinder for the accommodation within it of a piston-head 16 that is united to the piston-valve 12 as by an intermediate rod 17. A stud 18 projecting from` the inner face of the plug 4 is adapted kby impingement against it of the piston-head 16 to limit the opening throw of the valve 129whose clos-V ing throw is limited by the obstructing projection 19of the stop-seat 5. The stop or projection 19 is separated from the ring of vents 10 a suiicient distance to insure the perfect closure of the vents by the valve 12 before it is stopped by the projection 19.

Within a wall of the case 1, I provide two branches 20 and 21 of a by-pass that communicate, respectively, with the pipe 2 and through the body of the plug4 around the contiguous end of the barrel 6 with the interior of the piston cylinder 15. They communicate with each other through an auxiliary valve-shell 23 incorporated, preferably, withinthe case 1. A barrel valve of well known type 24 fits within the bore of the shell 23, and is adapted to be turned about its longitudinal axis, as by aid of a handle 25.

The valve 24 is provided with three vents 26, 27, and 28, so relatively disposed as to make connection between the by-pass branches 20 and 21 through the valve 24, as shown in Fig. II or to break such connection and establish communication .between the branch 21 and a relief vent 29 that penetrates the shell 23 at a point adjacent to the bore-expansion 9 of the case 1. Y

The main valve 12 of my invention is according to well understood principles driven by hydraulic pressure derived from the pipek 2. Delivered behind the piston-head 16 through the by-pass branches 20-21 said pressure, upon the turning of the valve 24, operates despite the liquid pressure in the pipe 2 against the piston-head 16 to drive the valve 12 towards the pipe 2, and to close the vents 10. The said eiiect is accomplished by reason of the inequality of the areas of the faces of the piston-head 16 and valve 12, respectively.

A special utility of my device is found in the bodily removability and renewability of the barrel 6. By this means, the main valve mechanism being contained wholly within the barrel, it is made possible at will to remove t'or repairs or to renew the barrel and its contained parts, without disturbing the case or its pipe connections.

What I claim is:

l. In a device of the kind described, the combination with a case, having a longitudinal bore provided with an enlarged recess, a barrel positioned in said bore having its opposed ends of different diameters, peripheral openings 'formed adjacent one end of said barrel, a united piston-valve and piston head mounted in said barrel, said piston valve adapted to control the flow through said openings, an auxiliary valve operatively associated with the barrel, means connected to said auxiliary valve for selectively regulating the iiow to either end of said barrel, a stop for limiting the closing throw of said piston valve when actuated by said auxiliary valve, said stop being separated from said radial openings to insure closing thereof by the piston valve before the latter reaches the said stop.

2. In a device of the kind described, the combination with a case provided with an expanded bore, an auxiliary valve shell, specified by-pass branches, spout, and relief vent, of a barrel located between the opposite ends ot' said branches and within said bore, said barrel being of two diameters and having a ring of vents into the case, a. united main piston-valve and piston-head Working in said barrel and fitting the respective diameters thereof, said piston-valve working across the ring of vents with snug slip lit to open and close them, a stop for limiting the closing throw of the piston-valve, said stop being suhciently separated from the ring of vents to insure perfect closure of the ring of vents by the piston-valve before it reaches said stop.

In testimony whereof, I have hereunto set my hand in t-he presence of tivo subscribing witnesses.
